. In Great Britain February 14, 1936 7 Claims.

This invention relates to means for changing the magazines of typographical composing machinesof the kind wherein a column of superposed magazines is adjustable between distributing mechanism and assembling mechanism to bring a selected magazine, or selected magazines, into operative relationship with the said mechanisms, or to bring a selected magazine into a position in which its delivery end is located above the assembling mechanism to enable the magazine to be removed frontwise over the assembling mechanism.

More particularly, the invention relates to machines comprising an adjustable magazine-supporting frame including a plurality of base-frame members one appropriate to each magazine of the column, and a fixed frame having side members between which the magazine supporting frame is adjustable.

The object of the invention is to provide improved means for supporting during removal any magazine of the column selected for removal by adjustment of the column, and which is automatically brought into active position for supporting the magazine at the front of the assembling mechanism through the forward movement of the selected magazine.

With this object in View, the invention consists in a typographical composing machine provided with an adjustable column of magazines, comprising, on a fixed frame in which the column of magazines is adjustable, extensible arms adapted to provide support, during removal, for the magazine which is, for the time being, in the plane of said arms.

The invention will be clearly understood from the following description of one form which it may assume (given, however, merely by way of example), and the description will be more easily followed by reference to the accompanying drawing, wherein:-

Figure 1 represents a side view, and

Figure 2 represents a plan View, of the relevant parts of magazine supports in a typographical composing machine according to the invention;

Figure 3 represents a section along the line A--A of Figure 2, and

Figure 4 represents a detail modification which may be employed in a device as shown in Figures l and 2.

In carrying the invention into effect in one convenient manner as shown in the drawing herewith, a rail I parallel with the magazines is secured along each inner side of the fixed frame and a magazine supporting arm 3 is mounted to slide against the inner side of each such rail I. For this purpose each arm 3 is formed at its upper end with an outwardly offset portion 4 dovetailed or grooved to embrace the top and bottom edges of the rail 1. 5

The lower end of each arm 3 is formed with an extension 5 offset inwardly, the upper surface of said extension having a groove 6 flared at its upper end, as shown, and located in alignment with a lug l on the respective side of the 10 adjacent magazine of the column. The grooved extension 5 of each arm terminates in a hook 8 which arrests the forward movement of a magazine being removed and permits such magazine to hang from the arms in a vertical position as shown in Figure 1.

The rail 5 is provided at its lower end with a stop 2 serving to limit the downward movement of the arm by engagement with the outwardly offset portion 4 at the upper end of the arm.

Each rail i also carries at its upper end a latch or detent 9 which normally retains the respective arm in its innermost position.

When it is desired to remove a magazine, the magazine supporting frame is raised or lowered to bring the desired magazine into the plane of the arms 3, and the operator slightly tilts the magazine at its front end to disengage a cross bar such as It on its underside from a recess H in the base frame, and draws the magazine 30 downwardly over the base frame until its laterally projecting lugs "I" engage with the grooves 6 in the lower part of the arms and contact with the hooks 8 thereof.

Further withdrawal of the magazine causes the arms 3 to move outwardly therewith, the weight of the magazine thus being transferred during the forward movement from the base-frame to the supporting arms. When the arms have reached the limit of their outward position as determined by the stops 2 at the lower ends of the rails, the magazine is clear of the magazine column and free to pivot in order to hang vertically from the hooks of the supporting arms.

The reverse operation takes place during the replacement of a magazine, except that the supporting arms 3 do not necessarily follow the rearward movement of the magazines, and may be returned to normal position by hand.

When the invention is applied to machines fitted with split magazines, (and more especially when this form of magazine is in any position in the column except at the top) it has been found that there is some danger in drawing forward the front portion of the magazine for removal, that it will slide off its supporting frame before the lugs have properly engaged the grooves 6 for support. In order to avoid this danger the arms 3 may be modified as shown in Figure 4. In this arrangement there is mounted upon a pivot l l on the outer side of the offset portion 5, or on the arm 3 adjacent thereto, a platform I2 which can be swung by hand to the position shown in full line, and thus provide intermediate support when the front portion of a split magazine is being removed. When the arm is in its innermost position the platform I2 is swung forwards to rest over the offset portion 5 as shown in dotted lines in Figure 4. When in this device a full size magazine is being removed, the platform must clearly be swung to the back (full line) position before the lugs 1 can enter the grooves 6, but this need not be done until the arms 3 have reached the outermost position determined by the stops 2 as the lugs bear against the edges of the platforms I2 (in the position represented by dotted lines) and thus move the arms.

It must be understood that the invention is not restricted solely to the constructional details of the forms described above, since various modifications may be introduced as they become desirable or necessary in order to carry the invention into effect under diiferent conditions and requirements which have to be fulfilled, without departing from the scope of the invention.

Having described my invention, I declare that what I claim and desire to secure by Letters Patent is:-

1. A typographical composing machine provided with an adjustable column of magazines, comprising, on a fixed frame in which the column of magazines is adjustable, extensible arms adapted to provide support, during removal, for the magazine which is, for the time being, in the plane of said arms.

2. A typographical composing machine comprising a fixed frame, a plurality of magazines in a supporting frame movably mounted in said fixed frame, and. arms on said fixed frame for supporting one or another of said magazines during removal or insertion, a slidable or telescopic member of each arm being adapted for engagement by, and outward movement with, a selected magazine being removed.

3. A typographical composing machine comprising a fixed frame, a plurality of magazines in a supporting frame movably mounted in said fixed frame, and arms having parts in slidable engagement with a rail of said fixed frame, adapted to support one or another of said magazines during removal or insertion.

4. A typographical composing machine comprising a fixed frame, a plurality of magazines in a supporting frame movably mounted in said fixed frame, and arms on said fixed frame for supporting a magazine during removal or insertion, a slidable or telescopic member of each arm being adapted for engagement by, and outward movement with, a magazine being removed, and grooved members on the outer ends of said arms adapted to receive lugs projecting from the magazine being removed.

5. A typographical composing machine as claimed in claim 2, wherein said arms have hooklike extremities in which a magazine can pivot in its outermost position.

6. A typographical composing machine provided with an adjustable column of magazines, comprising, on a fixed frame in which the column of magazines is adjustable, extensible arms adapted to provide support, during removal, for the magazine which is, for the time being, in the plane of said arms, and auxiliary supporting means positionable between the foremost supporting part of the magazine base, and the supporting elements of said arms.

7. A typographical composing machine according to claim 6, wherein said auxiliary means comprise platforms pivotally attached to said arms.
